This Saturday I will be attending an NHL hockey game and I'm unsure what settings I really need to capture images. I shoot mainly landscapes so this is new territory for me. I will be bringing my 7D II with my 70-200mm f/2.8L IS II USM. My niece got the tickets and I'm pretty sure they are in the uppermost part of the arena so I'm not sure the 200 will be long enough. I do have the EF 2x III extender but I'm not sure the lense will be fast enough with it attached. Any tips and or advice will be greatly appreciated. Thank you in advance.
